Tim Weaver 04/02/12 02:28 PM,I’ve been in the pro audio business for almost 20 years, but I never set out to be a sound system provider. But in 2008, after eight years working at a large university’s theatre complex, well, as Bob Dylan said, “one day the ax just fell.” I called all of my old friends but couldn’t find a decent gig anywhere. So I ended up mixing acoustic acts for next to nothing in a local bar and grill. This little bar… View this story

Ken DeLoria 03/13/12 04:36 PM,Be sure to read the first two parts of this series: —Making It Flat: Analyzing Loudspeakers & DSP—Harnessing The Power Of Digital Signal Processing ————————————————- Years ago, a couple of smart guys named Thiele and Small characterized the behavior of cone drivers. One of their many excellent contributions was identifying how an electrical filter (passive or active) can be combined with the electro-mechanical-acoustical parameters of a cone driver, in a properly ported enclosure, to extend and optimize low-frequency output capability. … View this story

Henry Cohen 03/09/12 10:52 AM,Rules for the operation of Television Band Devices (TVBD) in the core TV bands (low VHF – channels 2-6; high VHF – channels 7-13; and UHF – channels 14-51) were finalized in January 2010. One of the requirements of TVBD operations was the establishment of a working and real-time accessible geo-location database from which TVBDs had to receive a list of available TV channels based on the TVBD’s physical location and type. It’s only as of January 26, 2012 that… View this story

Dave Rat 02/13/12 06:09 PM,Prior to hitting the road with Soundgarden on tour last summer, Dave Rat documented his front of house racks. This collection of gear was deployed with a main system of L-Acoustics K1 line source (3-way) loudspeakers in flown arrays, K1-SB (2 x 15-in) subwoofers, and LA8 amplified controllers. Dave notes that some of the pieces were dictated by sub configurations he planned to use, while the Dorrough meters were on hand to provide clear visuals of average versus peak simultaneous… View this story

Teri Hogan 02/07/12 02:30 PM,Sound companies handle “one-off” shows every day. It’s usually formulaic, and after a while, we do it by rote. But what happens when the client wants one-stop shopping? This is also known as “full production” or “turn key service,” and it’s quite a bit more involved than an average show. Generally months of planning and coordination are needed, as well as work with a number of subcontractors. It just can’t be done by the seat of the pants. Normally, when… View this story

Tom Young 01/27/12 02:56 PM,A sound level meter (SLM) is a device used to make frequency-weighted sound pressure level measurements displayed in dB-SPL. 0.0 dB-SPL is the threshold of hearing, and is equal to 20uPa (microPascals). This correlates to what one would aurally perceive when in a deep cave or in a large anechoic chamber. Packaged as a single-function handheld test device, SLMs are intended to be held at arm’s length during measurements (to reduce the effects of the body on the measurements) or… View this story

Charlie Hughes 01/25/12 03:06 PM,The specification of a loudspeaker’s sensitivity is probably one of the most common, yet perhaps one of the most misunderstood. It’s common to see the magnitude response of a loudspeaker system reduced to a single number as a sensitivity rating. This is perhaps at the heart of the confusion. One would think that this metric should give some indication as to how loud a particular loudspeaker will be when reproducing a signal. One may also think that two loudspeakers with… View this story

Dave Rat 01/10/12 05:27 PM,Beauty in art revolves around the realization that there is no “correct” way for something to look, sound or feel. I believe this to be also true about the way audio is presented at a rock show. In fact, there’s a fairly wide range of possible sonic footprints which a sound engineer can offer the music to the audience while still maintaining an impressive auditory presentation. An even bigger challenge is to find a “sound and mix” that optimally compliments… View this story

Rick Kreifeldt 12/22/11 01:41 PM,Go ahead and see how much you really know or don’t know about Compression. This mini-test gets progressively more difficult and is a good indicator of where you stand in this area of pro audio science. Rick Kreifeldt, Harman Professional SDIG Vice President, has graciously guest authored a dynamics processing inspired Twenty Questions. There is one correct answer for each question. Good luck! 1.) What does a Compression Ratio of 4:1 mean? A.) Once past the threshold, the input… View this story

Jeff Berryman 12/19/11 09:14 AM,These days, concert loudspeaker systems can sound very good over most of the frequency range. Things have improved a lot in the last five or ten years. But to my ears, bass sound hasn’t made nearly as much progress. How often have do you go to a show, particularly a fairly loud one, and feel that you’re listening to a war between the upper and lower halves of the spectrum? It all sounds pretty good at low levels, but when… View this story
